Z36 subclade

I've tested my R1b-U152 haplogroup, with YSEQ, in order to deepen it (with Z36). The outcome is this:

What does this exactly mean?

You are positive for Z36 and it's common in Northern Italy. (Especially Lombardia)

What I don't understand is that the FAQ say:

How can I tell if I'm ancestral (=negative) or derived (=positive) for a certain SNP? "Go to the table of your results and check the allele column on the very right side. It shows the DNA base (A,G,C or T) that you have at the SNP position and a little plus (+) or minus (-) sign behind it. Plus means that you are derived for that SNP and minus means that you are ancestral."

Why do I get R+? What does it mean?

+ means you have it.
- means you do not have.

Yes, sure. The problem is that, according to YSEQ, I'm 100% Z36+ but it's uncertain if I have inherited this line by my father or by my mother: they said that, for its position near chromosome X, Z36 is not a reliable SNP for phylogeny and then it could be happened a X-to-Y gene conversion. To me it sounds quite strange, because if I'm, for sure, U152+ and I get a Z36+ result, is reasonable to think this Z36+ as a paternal subclade.

X does not influence Y at all.
Maybe you did confuse something.

This is what I mean:

"It is important for me to communicate that Z36 is a problematic marker for phylogeny. This has nothing to do with the testing process. This is only based on the human biology. According to today's knowledge Z36 is not reliable for phylogenetic interpretation because it may not be inherited in a direct male line."
